To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.
To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.
Air quality monitoring for regulatory purposes requires instrumentation, systems and procedures that meet international standards such as those described by the USEPA, MCERTS or the European Union. Ecotech offers solutions that meet this criteria.
Real-Time measurements of VOCs causing smells or adverse health effects. Monitoring of chemical contamination related to the Sick Building Syndrome. Sensory impact on passengers in aircraft cabins, cars (VIAQ) and workers in offices or family homes.
Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring. Cerex multi-gas analyzers offer significant advantages over single gas analyzer arrays, electro-chemical sensor arrays and time integrated air sampling hardware.
Source apportionment of pollution – establishing where pollution of a particular profile is coming from

Ambient air monitoring involves the measurement of `representative` air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.
To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from...

Reducing air pollution is a major challenge worldwide. ENVEA’s pioneering technologies help private, public and local authorities meet their air quality challenges and objectives. Over the decades, our engineers have been innovating, inventing, and modernizing tomorrow’s AQMS solutions to be in line with environmental standards and climate change challenges. Whether it’s for a single monitoring location, or a city or nation-sized air pollution monitoring network of reference multiparameter...
According to US EPA IO - 3.3 standard method of heavy metals, PMMS – 5000 uses XRF nondestructive testing technology and atmospheric automatic enrichment technology to realize the accurate measurement of atmosphere heavy metals such as lead, mercury, cadmium, chromium, arsenic, etc. It is widely used in environmental air quality monitoring places such as industrial pollution area, residential area, city, etc.
To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.
Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.
Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide (CO2), carbon monoxide (CO) and volatile organic compounds to particulates, humidity and bacteria such as legionella. CO2 is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying...
